Yeah, Fred's too big for the young Katie, but she still cums on him plenty when they find the right positions to bring her off. (When asked in the Behind the Scenes footage, she says she came four or five times.) Before that, she yanks the first orgasm from him in less than two minutes of screen time, even after he's pulled out a couple of times to try and delay his O. She's captivating him.

And look at the expression on her face beginning at 2:05 as she takes in his new, full erection! Awe, respect, fear...it appears as a real, candid reaction to 'Dingo's singular cock.
